I saw this quote when surfing the net today:
“The human race, to which so many of my readers belong, has been playing at children’s games from the beginning, and will probably do it till the end, which is a nuisance for the few people who grow up.” — The Napoleon of Notting Hill – G. K. Chesterton
Is that what PTerry and GNeil were talking about in Good Omens? The G.K Chesterton dedication before the story begins.
